The connecting end 33 of the adjusting rod 30 is slidably connected to the support frame 20. In the process of the adjusting rod 30 moving relative to the base 10 along its length direction, the connecting end 33 of the adjusting rod 30 slides relative to the support frame 20 and drives the support frame 20 to rotate relative to the base 10.

[0054] The LED display screen mounting device provided by this embodiment includes a base 10, a support frame 20 and an adjustment rod 30. The base 10 is matched with the display screen unit and installed. The support frame 20 supports the base 10. In order to ensure that the display screen unit is installed on a horizontal plane, an adjustment rod 30 is provided on the base 10. The adjustment rod 30 has a connecting end 33 and an operating end 34. By controlling the operating end 34 of the adjustment rod 30, the adjustment rod 30 can be moved relative to the base 10. Since the connecting end 33 of the adjustment rod 30 is slidably connected to the support frame 20, when the adjustment rod 30 is controlled to move relative to the base 10, the adjustment rod 30 drives the support frame 20 to rotate relative to the base 10, so that the angle between the support frame 20 and the base 10 can be adjusted. Further, when the ground is uneven, the support frame 20 can be driven to rotate by the adjustment rod 30 to adjust the position of the support frame 20, and then the position of the base 10 and the display screen unit is adjusted to ensure that the base 10 is in a horizontal state, which is convenient for installing the display screen unit, thereby improving the display effect of the LED display screen. With the above structure, the base 10, the support frame 20 and the adjusting rod 30 cooperate with each other. The base 10 is used to install the display screen unit.
